Zebra Chip identified in Idaho

Erik Wenninger, University of Idaho entomologist at the U of I Kimberly Research and Extension Center, reports that a single potato plant has been identified with classic zebra chip symptoms at the Kimberly R&E Center in Kimberly, Idaho.

Zebra chip symptoms include: aerial tubers, pink coloration on leaves, curling of leaves and characteristic internal discoloration of tubers.

Samples were sent to the University of Idaho campus for molecular testing to confirm the presence of liberibacter, the causal agent of zebra chip. However, based on symptoms, researchers are reasonably confident that the plant is positive for zebra chip.
